4.0.0

Fixed

• PHP dependency updated to support php v8.0 (thanks @freescout-helpdesk)
• Method return and argument types added
• Imap DONE method refactored
• UID cache loop fixed
• HasEvent::getEvent return value set to mixed to allow multiple event types
• Protocol line reader changed to fread (stream_context timeout issue fixed)
• Issue setting the client timeout fixed
• IMAP Connection debugging improved
• Folder::idle() method reworked and several issues fixed
• Datetime conversion rules extended

Breaking changes

• No longer supports php >=5.5.9 but instead requires at least php v7.0.0.
• HasEvent::getEvent returns a mixed result. Either an Event or a class string representing the event class.
• The error message, if the connection fails to read the next line, is now empty response instead of failed to read - connection closed?.
• The $auto_reconnect used with Folder::indle() is deprecated and doesn't serve any purpose anymore.
